## Signature Outcomes

- 289 API endpoints migrated (96% of production traffic, 5-domain architecture)
- $336K annual run-rate reduction (cloud $278K + observability $26K + database $32K)
- 95% MTTR reduction (via Redis/Xdebug/BPF debugging platform, incident logs)
- 34 parallel AI agents (concurrent validation with deterministic boundaries)
- <10 minute migrations (per endpoint, down from 4+ hours, with human checkpoints)
- 98% uptime (during 50% global traffic cutover)
- 45+ migration specs (reverse-engineered from legacy Acucobol bytecode without source access)
- 558 peer recognitions (high-frequency validation loop over 2 years)
- 185+ 1:1 mentorship sessions (3 engineers promoted to Senior/Staff)
- Scaled platform 100x during COVID, 10x traffic surge, zero incidents
- Led teams processing $2B+ in transactions
- Pioneered GPT-3 implementation (2022, pre-ChatGPT), saving ~2 hours/week/employee
- Patented mobile asset caching algorithm (Process Patent, 2012)

## Core Expertise

- AI/ML: Model Context Protocol (MCP), Context Engineering, Multi-Agent Orchestration, RAG, Constrained Autonomy
- Platform: Kubernetes, AWS, Azure, Terraform, CI/CD, Observability (Datadog, Redis, BPF)
- Architecture: Microservices, Event-Driven, Domain-Driven Design, Legacy Modernization, Strangler Fig
- Leadership: Technical Strategy, Cross-Team Coordination, Executive Partnership, Mentorship
- Languages: TypeScript, Python, PHP, SQL

## Operating Principles

- Reversibility before speed
- Auditability before autonomy
- Defaults that reduce blast radius
- Mechanisms that survive turnover
- Tools engineers opt into (not mandates)
